IMPROVEMENT IN ENVELOPES.

Specification forming part of Letters Patent No. 185,420, dated December 19, 1876; application filed August 3, 1876.

To all whom it may concern:

Be it known that I, ALFRED S. ADDIS, of Anaheim, county of Los Angeles, and State of California, have originated and invented a new and useful Improvementin Envelopes, of which the following is a specification:

The object of my invention is to form an envelope, which Iclaim is security against all attempts to open or tamper with said envelopes without leaving evidence of same.

The envelope is folded so that the tongue of said envelope goes through and into the different parts of, envelope through slits or cuts for the purpose. The main tongue passes through the slits, and coming out again folded around the edge of envelope, returning again into the slit in said tongue made to receive it, the whole being sealed or gummed together as is usual with envelopes. Then over the slits or cuts and tongue is placed a seal similar to a notary seal with name of government office, or firm, or private individual, either in raised or sunk letters, or both, thus securing the same from opening, or tampering with same without leaving evidence of same, thereby leading to immediate detection.

The improvement is more fully set forth in the following specification, reference being had to the accompanying drawings. Below is a full description of same.

Figure 1 shows the shape of the envelope when opened out, a, a a a a showing slits or cuts through which the tongues B B B pass when folded, as shown in other drawings. Fig.

2 shows the envelope partly folded; a a, two of the slits still vacant, showing B B two of the tongues in proper place, when they are sealed with gum arabic orother substance; also B still unused that passes through a a, as more fully shown in Fig S. Fig. 3 shows the envelope still farther folded, showing where tongue B has passed through slit a, still leaving one of the slits a vacant, through which passes the end of tongue B, as more fully shown in Fig. 4. Fig. 4 shows the envelope fully folded, all the different tongues in their places ready for final sealing, showing where the tongue runs into slit a. Fig. 5 shows the reverse of envelope, when all properly folded, with the final seal 0 placed over the slit and tongue that runs into the slit, thus sealing all parts completely together, rendering all secure.

What I claim as my invention is- The envelope herein shown and described, having in its center fold and top, side, and bottom flaps the slits a, and upon its top and side flaps the tongues B, said tongues being constructed as shown, so that when folded those upon the side flaps shall take into the slits opposite, and the one upon the top flap shall pass through the slits in the bottom flap, centerfold, and top flap, substantially as shown and described above.
